Methods and Systems of a Dedupe File-System Garbage Collection

1. A computerized system of concurrently synchronizing a garbage collection thread and a writer threads in a dedupe file system in a data gathering state comprising: a processor configured to execute instructions; a memory containing instructions when executed on the processor, causes the processor to perform operations that: while the dedupe file system is in a data gathering state, a garbage collector thread concurrently working with writer threads, generate, with at least one processor, a garbage list of data chunks that are candidates for deletion by a garbage collector thread, wherein the garbage collector thread enumerates all backups on the data store, and wherein the garbage collector thread traverses a list of valid backups and removes any data chunks of the list of valid backups from an eraser database of the dedupe file system; and with the writer threads, referring to the garbage list of data chunks while ingesting data by: matching the data chunks with those present in the garbage list; filtering out the matched data chunks from garbage list of data chunks; setting, with the garbage collector thread, the dedupe file system to a data deletion state; and setting the writer threads to ingest data into the dedupe file system in synchronization with garbage collector thread.

2. A computerized system of synchronizing a garbage collection thread and a writer threads in a dedupe file system in Data deletion state comprising: a processor configured to execute instructions; a memory containing instructions when executed on the processor, causes the processor to perform operations that: provide one or more writer threads concurrently working with garbage collector thread, referring to the garbage list of data chunks while ingesting data by: matching the data chunks with those present in the garbage list; for the matched data chunk add one or more hard links to the data chunk file in a temporary location, and wherein the hard links lock the data chunk file from deletion, wherein the hard links are a directory entry that associates a name with a data chunk file on a file system of the computerized system; with a garbage collector thread: iterate through the garbage list; and obtain an exclusive access of each data chunk and delete any data chunk that is not marked by the one or more writer threads as having two hard links.
